Foreword by Captain Grant Headifen. Enough years ago, so that this story can be attributed to youth rather than present day embarrassment, we set off from St Bart's in the Caribbean to St Eustatius. While most islands in the Caribbean can be navigated by line of sight, with this passage, St Eustatius is over the horizon and so proper navigation techniques were required.
This was my first Chartering experience and as Captain, I was responsible for 6 crewmembers lives and, of course, the vessel. A quick check of the charts revealed that St Eustatius was slightly west of a due south heading and was about 25 miles away, at 6 knots that would take us about 4 and a bit hours. Simple enough. Up anchor and hoist sails. Yet three times in 1/2 an hour increments something inside me was questioning my rudimentary assessment of the navigation ease. Finally on the third visit to the charts, I spotted the compass rose and thus the source of my anxiety. At that position on the planet the difference between the chart's definition of north and the compass reading of north is different by nearly 15 degrees.
Whoops! A simple but amateurish mistake. Time to get serious. Now more skillful techniques had to be called upon. A new and real position had to be calculated based on the 1.5 hours of incorrect heading and the average maintained speed. Then a new plot direction had to be established to St Eustatius based on our new determined position. To double confirm that newly determined position I triangulated our position by taking compass shoots off various islands. Back on track, we thoroughly enjoyed the rest of our vacation with a lesson never to be forgotten!
Such amateurish mistakes can lead to serious consequences. What if there had been a reef on our mistaken course? Get the picture?
Captain Ed Mapes' Coastal Navigation Clinic, as you'll discover, is one of those "oh durh could have had a V8" moments because of his reduction of the seemingly intimidating world of marine navigation to an exciting understanding and confidence in your knowledge to now - Navigate. He has turned intimidation to inclination. Inclination to get out and really practice and use your new skills.
You'll leave this Coastal Navigation Clinic with an understanding of:
- The Charts and how to use navigation tools
- True north and magnetic north - and variation and deviation
- Determining your position using various techniques such as dead reckoning, running fixes and triangulation
- What to do with your GPS position to get you to your destination
- Set and drift from wind, tides and current
- How to simply determine your heading based on Set and Drift
You'll then run through real exercises to build your confidence. In the first Module we'll introduce you to Landfall Navigation where you can mail order globally ($10 +S&H) a practice chart for the confidence building exercises and the test. The test grades in real time - so that once you've passed - you'll have your Navigation Certification in hand immediately.
Register for the NauticEd Coastal Navigation Clinic now and as an incredibly FUN BONUS, we'll give you a GPS treasure hunt formula that you can use to set up in your neighborhood park for an enjoyable family and friends navigation picnic. Remember, with NauticEd, you can return as many times as you like to brush up on your navigation skills for FREE.
There are possibly only a few things more fun than scooting along the ocean taking compass sights off islands and using dead reckoning and running fix skills to determine your position and then calculating your ETA. One of those things is actually meeting your ETA, then celebrating with a cold drink and your feet in the sand.
Please enjoy Captain Ed Mapes' Coastal Navigation Clinic. As with all NauticEd online sailing lessons, if you don't feel as though you received the value for this Coastal Navigation sailing class, we'll simply refund your $39 investment back to you. With thousands of happy NauticEd students however, we doubt that will happen.

Excerpt from the course
You are sailing along on a heading of 57° psc (61° Mag) (47° T), your knot meter reads 5 knots. You are passing Horton Point Light to your starboard. At 1548, a hand held bearing shows that the bearing to Horton Point Light is 119°Mag (105°T). You decide to do a running fix. At 1615, the bearing to Horton Point Light is 160°M (146°T). Determine your running fix position.
Watch the animation then read the text then watch the animation again.
The time elapsed is
1615 minus 1548
1575 -1548 = 27 minutes (/60) = .45 hours
At 5 knots you will travel 5 x 0.45 = 2.25 NM
You draw the true bearing line of 105° T to Horton Point Light. You then draw a vector 2.25NM long in a direction of your heading 47° T starting anywhere on the 105° line. You then draw another line parallel to the first 105° T bearing that intersects the end point of the 2.25NM vector. Finally, you draw in your second bearing line of 146° T. Where the 146° T line intersects the parallel 105° T line - you mark as your running fix position.
The theory behind this is simple but not usually explained. Initially you must lie on the 105-degree line somewhere but you don't know where. You know that over the time elapsed you will travel the 2.25 NM from somewhere off the initial 105-degree line but you don't know where - yet. The parallel 105 deg line projected forward means that you will also lie somewhere on that projected line - again -somewhere. By doing the second bearing - off any object - the intersection of that bearing with the projected line means you must be at that point (given that your speed and heading where accurate).
Answer - LAT 41° 06.1' N and LONG 72° 27.0'W
